"I am hoping for a speedy recovery," fellow '80s musical superstar Cyndi Lauper said, according to E! Online. "He is a strong-willed person, so I am feeling very positive that he will pull through like a champion. My thoughts are with his family."

While Australian chef Curtis Stone had it out for Bret during a previous "Celebrity Apprentice" challenge that involved a country-star makeover, he had nothing but kind words for the rocker. "He's a nice man, and I've got great wishes for him," Stone told E!.

WWE Diva Maria Kanellis is also pulling for the "Rock of Love" star. "All you can do is hope and pray for him and his family," she said. "He's a strong man, so I hope he recovers very quickly."

As for "Celebrity Apprentice" boss Donald Trump, he told TMZ that Michaels is in "big, big trouble and the prognosis is not great."

"He turns out to be an amazing competitor, and ultimately, that is the thing that could save his life," Trump said.

The latest update from Bret's camp on BretMichaels.com said the singer's condition hadn't changed: "As of now Bret remains in ICU under 24 hour surveillance. Further testing this week will help locate the source of the bleeding."
